品名:矿用卷扬机
卷扬机又叫绞车,主要有下列几种:
手动绞车
手动绞车的手柄回转的传动机构上装有停止器(棘轮和棘爪),可使重物保持在需要的位置。装配或提升重物用的手动绞车还应设置安全手柄和制动器。手动绞车一般用在起重量小、设施条件较差或无电源的地方。
电动绞车
电动绞车广泛用于工作繁重和所需牵引力较大的场所。单卷筒电动绞车(图)的电动机经减速器带动卷筒,电动机与减速器输入轴之间装有制动器。为适应提升、牵引和回转等作业的需要,还有双卷筒和多卷筒装置的绞车。一般额定载荷低于10T的绞车可以设计成电动绞车。
液压绞车
液压绞车主要是额定载荷较大的绞车,一般情况下10T以上到5000T的绞车设计成液压绞车。

Winch and winch, basically have the following several kinds:
Manual winch
Mounted on the manual winch handle of rotary actuator stop (ratchet wheel and pawl), can keep the weight in the location of the need. Assembly or ascension weight with manual winch should also set up the handle and brake. Manual winch generally used in the small weight, establishment conditions with poor or no power.
Electric winch
Electric winch is widely used in heavy work and the required traction larger places. Single drum electric winch (figure) of the motor through reducer drive drum, between the motor and reducer input shaft is equipped with brake. To meet the needs of the ascension, traction and turning operation, there are more than double drum and drum gear of the winch. Generally rated load is lower than 10 t winch can be designed electric winch.
Hydraulic winch
Hydraulic winch is rated load larger winch, usually more than 10 t to 5000 t winch hydraulic winch.
